     1.  A circuit is a pathway for electricity to flow.

     2.  Circuits are used in electronic devices, robots and machines to make them work.

     BASIC CIRCUIT SIMULATIONS

     In Tinkercad, a simulation is the process of testing and visualising how a circuit works in a virtual
     environment. Instead of using real-world components, you can design your circuit and see how it
     behaves on your computer screen.

                     A new circuit design workspace will open.
     TURNING ON AN LED USING A BREADBOARD
                     Now, recreate the circuit by dragging the components (LED, Coin Battery, Breadboard, Resistor)
     To build a circuit that turns on an LED using a breadboard, you will need the following components:
                     from the components library and placing them on the breadboard.

     LED  The LED (Light Emitting Diode) converts electrical energy   Step  5   Connect the positive terminal of the coin battery to the breadboard’s positive rail.
     into  light. It has a longer leg (anode,  +) for positive
     voltage and a shorter leg (cathode, -) for negative.  Step  6   Connect the negative terminal of the coin battery to the breadboard’s negative rail.
                     Step   7    Connect the resistor to the battery’s positive terminal and the LED’s anode.
     Resistor  A resistor  controls the flow  of electricity  to  prevent
     damage to circuit components. It is used to adjust light   Step  8   Connect the LED’s cathode to the negative rail.

     Battery  A battery stores and releases energy to power a circuit,
     converting chemical energy into electrical energy.

     Breadboard  A breadboard is used for building and testing circuits
     without soldering, allowing easy placement and changes                                      To insert a note: N

     of components.

     Jumper Wires  Jumper wires connect circuit parts, allowing electricity
     to  flow between  components.  They  are  colour-coded,
     with red for positive and black for negative.  The output  shows the  LED lighting  up,  indicating  that  the  circuit  is  correctly  connected  and

                     functioning as expected.
